Calistoga is one of the country's historic spa towns, thanks to its natural geo-thermal hot springs. People have been flocking to this northern Napa enclave for decades to bathe in the rejuvenating mineral waters. Like the other resorts in the area, Calistoga Ranch has embraced the area's natural beauty and healing powers in a more refined, luxurious way. The resort's spa, The Bathhouse, reinvents the classic idea of "taking of the waters," as a way to restore balance to a person's body and psyche. The setting of The Bathhouse is serene, and includes soaking pools looking out over a creek and stands of mossy oak trees.
